LICHALP

Miriquidica atrofulva (Sommerf.) A.J. Schwab & Rambold

Syn.: Lecidea atriuscula H. Magn., Lecidea atrofulva Sommerf.

Lichenised.

Substrate: metal-rich siliceous rocks, siliceous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a circum- and bipolar lichen of metal-rich rocks, with optimum near and above treeline; mostly sterile and therefore perhaps overlooked in the Alps, but never common.
